`The invention consists of a trash incinerator' an object of which is the expeditious and consummate burning of trash with a minimum dis- I persal of residua and sparks.

It is well known that metal trash burners are unsatisfactory for many reasons but particularly because their usefulness is short-lived. AWith the present invention I have found that a burner body may be used, constructed of a durable lasting material, the body being mounted in a manner to effect extremely rapid and complete burning of the trash; the body is constantly maintained spaced from the ground and is rotatably mounted especially to permit the trash to be initially ignited at the top of the incinerator body preparatory to inversion of the body for effecting burning of the trash from the Abottom of the body.

It is also an object of this invention to provide an imperforate cylinder, each end of which is equipped with a movable grate, the cylinder being rotatably mounted on a supporting structure and adapted for reception on either end with a hood through the top of which smoke from the burning trash is exhausted, means being carried by the hood for engaging the same with and disengaging the hood from the body, the means also being operable into' engagement with the body to lo-ck the latter from movement.

Other objects of the invention will be apparent from the following description of the present preferred form of the invention taken in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of a trash incinerator constructed in accordance with the I present invention showing the hood in partly opened position, a portion of the body of the incinerator being broken away to disclose details.

Figure 2 is a detail fragmentary vertical sectional view of the incinerator body showing the hood in a closed position; and v Figure 3 is a detail fragmentary side elevational view of the incinerator showing the lower portion of the incinerator body, the air deector and the base of the frame.

The device of the present invention ilncludes a frame generally designated 4 which consists 4of a lbase 5 with vertical uprights 6 and l arranged in parallel relation, upright I projecting upwardly in a plane beyond the top of upright 6.

Supported by the uprights 6 and 1 is an imperforate cylinder or trash receiving body 8 made of metal or like material havingV open ends in each of which is mounted a grate 9. Each grate consists of a ring with a recticulate body, the

diameter of the ring being such as to lit snugly within the body Each of the grates carrya bar I9, one end of which is pivotally engaged, as indicated at II, to the outer periphery of the cylinder 8, at a point adjacent its terminal. The opposite end l2 of each bar extends beyond the body and serves in 'a dual capacity of a handle for manipulating the grate and a means for securing the gratefrom casual displacement. The free end of the bar is provided with a perforation I4 which complements openings formed in ears I3, the openings in the earsand the perforation in the bar being adapted for the reception of a body carried pin I5. The body 8 is rotatably mounted in the frame 4 through the instrumentality of shafts I6, one end of each shaft being secured to a plate II carried by the body 8 while the other end of each shaft is journalled in one of the Vertical uprights. To facilitate rotation of the cylinder on the shaft I5 handles I8 are provided, as advantageously illustrated in Figure 1. The inner periphery of the body 8 is fluted in a suitable manner in order to prevent the adherence of the waste material to the inner ywall of the body. In the present instance I provide staggered ribs I9 which preferably extend completely around the inner wall of the body 8 from the opposite ends of the latter. The elongated upper end of the upright 'I has pivotally engaged thereto an arm 2) one end of which is secured to a hood 2I. sliding engagement over either end of `the body or cylinder 8.

The hood 2l is preferably of truncated cone shape, the upper end thereof issuing into a flue 22 upon which a handle 23 is mounted. If desired, the handle may be insulated. Manipulation of the hood 2I through the handle 23 causes the arm 20 to be moved in an arc as described by the arrow in Figure l. When the hood 2I is moved into an extreme open position the free end of the arm 2U will ilex into either one of a pair of resilient clamps 24, the U-shaped clamps being arranged in vertical alignment on the outer wall of the body 8 as shown in Figure l. It Will be noted, upon reference to Figures 1 and 2, that the base of the hood is annular and provided with parallel recesses 25 in which either one of the bars I il is adapted to lie when the hood is in a completely closed position as shown in Figure 2.

The invention also includes an air deilector 26 which is carried by and extends upwardly from the base 5 of the frame immediately beneath the body or cylinder 8. Preferably the deflector 26 lThe hood is adapted for is of inverted V shape in cross section and secured to the base as shown to advantage in Figure 3.

In use of this device the body or cylinder 8 is positioned vertically as shown in Figure 1 after which the hood 2| is moved by the arm 20 until the free end of the latter engages one of the clamps 24 thereby locking the body from movement on the shafts I6. After this, the pin I having been removedfrom engagement vviththeA ears I3 and the bar I0 the free end of the latter is moved upwardly carrying with it its grate, leaving the upper end of the body open for the reception of trash. After the trash has beeny deposited in the body 3 and ignited from the top, the bar Il) is moved until the grate is en'-V gaged with the top of the body following which the pin I5 is inserted through the openings in the ears I3 and the free end of the bar. The arm 2U is then disengaged from its clamp 24 andthe body B..is rotated on the shafts Ifuntil the body isV inverted. In this `way the burning trash isrfpositioned at the bottom of the Vbody or cylinder and the hood 2| is engagedfwith; the top of the body in an obvious-mannen The air deector 26 tends tospread air at the bottom of the: body to effect; a controlled draft through the latter `for. completeburning ofv the contents of the body. At theY same time the smoke is-permittedvto pass through the ue 22 and residua'` are arrested in an apparent manner;

Various changes may be made in this; invention within the f scope of theclaims lappended hereto.

Whatl claim'is:

l.sA trash incnerator including a. frame, a'- trash receiving body, reversibly mountedv on 'the` frame, a movable-grate on each end of the body,

a hood-carried bythe frame vand engageable withand: over either rend ofthe body, and.` means for moving the .-hoodrinto engagement withxand out 3. A trash incinerator including a frame, a trash receiving body reversibly mounted on the frame, a grate hingedly mounted on each end of the body, a hood carried by the frame and engageable over either end of the body, means carried by the hood and movable into engagement with the body to secure the latter from movement, and means mounted on the frame in close proximity to the lower end of the body for deecting air passing into the 1body.

4. A trash incinerator, including a frame, a trash receiving body reversibly mounted on the frame, a grate hingedly mounted on each end of vthe bodyua hood carried by the frame and engageable over either end of the body, an arm connecting said hood to the frame, and clamps on the body andengageable with said arm to hold the hood in an open position.
